To all whom it may concern: v

Be it known that I, FRANK HA-US. a citizen of the United States, residing at Metropolitam'inthe borough of Queens and State of New York, have invented a-new and useful Improvement in Pipe-Couplings, of which the followingis a specification.

This invention relates to an improvement in pipe couplings and has for its object to provide a cheap and a simple, but highly-efficient device for uniting the abutr ting ends of pipes. 'Another object of my invention is to 'provide a de-v vice that is capable of adjustment so that the meeting endsof two pipes may be securely united shouldthey be of greater or less length than is actually required for a fitting."

- The invention also comprises certain details of construction and noveltiesof combination and-arrangement as will be particularly described in the following specification and pointed out in the claims, reference being had to the drawings; in which: 7

Figu re l is a perspective view illustrating thepractical application of my invention. Fig. 2 is a sectional view of the same. I FigsQ'B and 4 are detail views in perspective of the cast-iron flanges partlybrokeu away. Fig. 5 is a sectional elevation of one of the brass seats.

' 7 Fig. 6 is an end view of the same. Fig. 7 is a sectional elevation of the co-acting seatand, 8 is an end view of the same. a

' In carrying out my invention I employ two castiron collars A. and B, each having a left hand threaded opening A, and B cut centrally therein and surrounding the threaded-opening and upon'the outside of each a portion of its length with a left hand thread to encollar I provide a boss A and B Thecollar B. is

provided with iournon-circular bolt openings B and the collarAr, is provided with a similar number of 'circular openings A which are in line with the openings B and throughwhich project bolts C, each having a non-circular portion arranged adjacent its head,

and each having a nut C operating on its free end.

Fitting in the threaded openingof the collar A, is a brass ring or seat D. which is provided exteriorly for gage'the left hand thread of the collar A, and interiorly with}; right hand'thread into which is adapted to screw the one end of a pipe P. This ring or seat is also provided with a shoulderD. at one end which is adapted to fit within the recess A. formed in the inner face-oi the collar and the outer face of the ring is beveled as at D? to provide a bearing. surface for the beveled bearing surface E. of the ring or collar E, which is similardin' other respects to the ring or seat-B,- and which isadapted to screw into thethread portion of the collar B. This ring E, is also provided with an interior right hand threaded end into which screws the abutting'end ot a pipe section 1?. j f;

The rings or seats D, and E, are provided upon their interior withfshort studs or projections D and E respectively whichbprovide a gripping surface for wrench. or other tool which facilitates each ring being I quickly and easily adjusted into position. In operation the rings orseats arefirst screwed into its respective collarand the ends oi the pipes are then screwed into -'the rings, the bolts are then inserted through the openings'in the collars andby screwing up the nuts, the collars are drawn together which brings the beveled face of'one ring into contact with'th'e beveled face of the other ring, and by tightly adjusting the 4 nuts a firm tight joint or union'is established between;

the pipes.

faces. I I

' Having thus fully described my invention, what l claim as new and desire to secure by Letters Patent is:

A pipe coupling comprising. iron collars having ,bolt

openings, said collars having bosses on their outer faces,. and being interio'rly threaded, oppositely beveled brass.

seats fitting in said collars, said. seats having exterior and interior threads, inwardly extending studs carried by the seats and bolts connecting the collars.
